Databind a dataContext on another Xaml window?

Just in case some one is searching for the answer...this is how i achieved

Deaclaring the Datatable dtable was the crux of my solution .

Code on The searchWidnow.Xaml

public partial class SearchWindow : Window
  {

  public  DataTable dtable { get; set; }

  public SearchWindow( )
  {
  InitializeComponent();
  }


  private void Window_Loaded(object sender, RoutedEventArgs e)
  {

  // var dt = MainWindow.DataContextProperty;

  }
 
 
  private void bind_Click(object sender, RoutedEventArgs e)
  {
  var dt = this.dtable;
  dGrid2.DataContext = dt.DefaultView;
 
  
 

  }


Then on the mainwindow.xaml.cs page

In the button click event that opens searcwindow.xaml

if (dt.Rows.Count > 0)
  { 
 
  SearchWindow searchWindow = new SearchWindow() { DataContext = dt.DefaultView };
  searchWindow.dtable = dt;
  searchWindow.Show();

  }
